To a-ZZi/Jiomz't may concern.: f

Be it known that l, .keine F i'iiiiiiniii7 a citizen ot the United States., and `resident of l-lutchinson, in the county of BenoandState of lansas, have inventedcertainfnew` and useful lnipiovemente in Windmill Gearing',`

of which the following is a specification.

This invention relates to power transmitting devices and'inore particularly to a means for converting a rotary into areciprocatory motion. l i

fin important object of this invention is to provide a windmill gearinghaving novel means whereby the pump rod caused 'to re cipi'ocat'e with a uniform and steady move-y ment thereby eliminating the possibility of serious breakage of the parts and excessive A further object of thisinvention resides' in the novel form `of housinguwithin which.,

the-power transmitting members operate.

Specifically this invention is an improvement over my co-pending application Serial Number 510,798 'n `that it provides simple and reliable means whereby the pump vrod is r `maintained inapproXimate alineinent `with the main power transmitting gear so that'the` strain on the parts is reduced `tofa minimum i and so that lost motion is also reduced to a' minimum. By reason of the .improvement described the housing `.or casing may be Figure 2'is` a vertical sectional View through the same.

F'gure 3 is ahorizontal sectional view taken on line 3-3 of Figure 1.

Figure l is a front elevation of a modified 5o form of the invention.

Figure 5 isa horizontal sectional view ktakenon line 5H-.-5 of Figure 4. .Figure` is adetail View of a outer portions rack from contactfwith the back 14. -base 17 ofthe elongated rack 12`is extended y completes its stroke inv bracket eine` bodied in the invention, which bracket is used in connection with a spring embodied in the invention.

in thedrawing thenumeral 5 generally designates a housing which is cast in one piece'and is of elongated formation. The housing has its sides formed with a continuous outwardly extending projection consti tutiiig a reinforcing member 6 and a con-` tinuous channel 7 .through which a power transmitting gear 8 travels. rlliith'reference to Figures 2` and 3 yitwill be seen thatithe of the gear travel in the gear channel 'l' and that the hub 9 of the 4gear 8 `rotatably contacts with the flanges l() and 11 on opposite sidesof the channel 7 `Arreola 12 of elongated formation is secured within the housing by means of bolts .13 which pass through the back 14 of the housing.

The rear side of the elongated rack 12is `provided with` bosses 15 whichcooperate with the flangesV '16 formed at the edge of the `iaclr in `spacingthe :body of Epe beyond the teeth V1S of the rack so as to form a. gear 'contactjand guiding surface.`

. A. cover plate 2G is firmly p elongated rack 12` and entends `beyond the saine to cooperatewith the extended portion of `the base `in providing a second channel arranged in close ielationto'the channel 7 `and slidably receives a portion of the power transmitting gearS so that the gear will be correctly guided. The end portions ofthe cover' ,plat-e 20 are extended outwardly .to provide a flange 21 which is arrangedinthe hub' 9 ofthel gear. i Specifically the of oval-shaped formation to slidably receive and guide one of the hubs -9 of the gear.

The gear 8 is rotated about the stationary `axis passing through the drive shaft 24 of the usual wind wheel.

lt is thus seen that the` operation of the gear' Swill cause the housing to move vertically and laterally and thereby reciprocate the pump rodL 26.

The pump rod 26 has its 1upper end `formed with a pair'of spaced arms 27 `to which a pulley 28 is connected. the said pulley -being slidahlefin aislot 80 ,ina depending por@ secured to the `anges 10 and 21 provide' acontinuous slot ioo tionBl of the housing.v The pump rod 26 isv i 9o wardly'ofthe flange lOand contacts with f` at all times arranged directly beneath the gear 8 so that the strainon the several parts is uniformly distributed.

In operationthe housing is suspended by a coiled spring-35 connected at its upper end to a bracelrt 86. The coiled spring 35 serves as a steadying means for the housing'and also holds the housing vin yposition in the event oi breakage ot the gear 8 onthle drive shalt ln this manner the housingoould '-'be prevented from falling onto some other part oi the Wind Wheel tower and possibly breaking the saine. i

The several parts of the power transmitting device may be readily and conveniently reversed when partly Worn'so that the wear will be uniformly distributed.

, As illustrated in FigureA l. the depending portion 3l is pro fided with a bracket 90 held in position by a cap screw 91the said bracket being formed with a disc shaped head 92 With which one end of a coil springv n 93 is'enga'ged. The other endet the coil spring `93 bears against theL end ot the pump Arod 26 and thereby serves as an etticient and positive means for alining the pump rod with the gear 8 so that the lateral movement;

of the housingiis facilitated, vvhen it reaches the endzot1 this stroke. It isl obvious, of course, that the gearS does. not `move vertically, but that the/housing 5 is the movable `member and travels in an oval path. yHovvever, the movement of the pump rod 26 is substantiallyvertical because of the presence of the coil spring 93. l

In. carrying out the invention the coil spring 93 may be located Within the dependingportion 31 so as to save space.
